In polar coordinates, the origin is called the pole.

Explanation:

The position of a point in a polar coordinate system is defined by using the distance from a fixed point and an angle made with a fixed ray from that point. It is a two-dimensional coordinate system.

The polar coordinates is defined as

Where, r is radius and θ is the angle with the polar axis, i.e. positive axis.

In a coordinate system (0,0) is called origin.

In polar coordinate system (0,0) is called pole.

Therefore, in polar coordinates, the origin is called the pole.
